Description

Technical Field

[0001] This utility model relates to the field of wire rope performance testing technology, and in particular to a wire rope bending test machine. Background Technology

[0002] In modern industry, steel wire ropes, as key load-bearing and transmission components, are widely used in numerous scenarios such as marine engineering, mining, and construction. However, these actual working conditions are often extremely complex and harsh, requiring steel wire ropes to withstand long-term exposure to extreme environmental factors such as temperature and humidity changes, salt spray corrosion, and water pressure, significantly increasing their performance degradation and failure risk.

[0003] Traditional wire rope bending testing machines primarily focus on testing single mechanical properties. Even those machines that consider environmental factors can only simulate simple, single environments, such as high temperature or high humidity. In practical applications, the environment faced by wire ropes is not isolated but involves multiple factors that interact and influence each other. The mechanism by which these multiple environmental factors affect wire rope performance is extremely complex. Existing testing machines struggle to meet the needs of in-depth research and precise evaluation, resulting in wire rope bending tests failing to comprehensively and realistically reproduce the multi-environmental coupling conditions encountered in actual use. Utility Model Content

[0004] Therefore, it is necessary to provide a wire rope bending test machine to address the problem that existing testing machines cannot meet the needs of in-depth research and accurate evaluation, resulting in the inability of wire rope bending tests to fully and realistically reproduce the multi-environment coupling conditions in actual use.

[0005] A wire rope bending testing machine includes: a testing mechanism, which includes a testing platform, a sealed box, a bending wheel, and a drive assembly for moving the bending wheel; the sealed box is disposed on the upper surface of the testing platform. A connecting mechanism, comprising an outer locking ring, an inner locking ring, and a mounting assembly, wherein a steel wire rope is provided between the outer locking ring and the inner locking ring; A salt spray system, comprising a nozzle and a water tank; A temperature and humidity monitoring mechanism, wherein the temperature and humidity monitoring mechanism is located on the outside of the sealed box; A hydraulic pressurizing mechanism, comprising a pressurizer and a connecting pipe.

[0006] In one embodiment, the mounting assembly includes a connecting post, a sealing disc, and a limiting block. The connecting post is connected to one side of the outer locking ring and the inner locking ring, respectively. The side of the sealing box has a moving groove corresponding to the outer locking ring and the connecting post. The sealing disc is located on the side of the outer locking ring away from the inner locking ring, and the sealing disc is located outside the sealing box.

[0007] In one embodiment, two sets of limiting blocks are provided, and the two sets of limiting blocks are fixedly disposed inside the sealing box. The limiting blocks are convex blocks, and the outer locking ring and the inner locking ring are both provided with limiting grooves corresponding to the limiting blocks on their sides.

[0008] In one embodiment, the drive assembly includes a mounting frame, a motor, and a lead screw. The mounting frame is fixedly disposed inside the sealed box, the lead screw is rotatably disposed inside the mounting frame, and the top end of the lead screw rotatably penetrates through the sealed box. The motor is disposed on the upper surface of the sealed box, and the output end of the motor is keyed to the top end of the lead screw.

[0009] In one embodiment, the drive assembly further includes a connecting rod and a moving block, the moving block being configured as a convex block and threaded onto the outer arc surface of the lead screw, the moving block being connected to two sets of bending wheels via the connecting rod.

[0010] In one embodiment, the outer locking ring and the inner locking ring are located between two sets of bending wheels, and the outer locking ring, the inner locking ring and the bending wheels are located on the same vertical plane.

[0011] In one embodiment, the water tank is located on the side of the sealed box, the nozzle is located inside the sealed box, and a water pump corresponding to the nozzle is installed inside the water tank.

[0012] In one embodiment, the pressure device is disposed on the upper surface of the test bench, and the pressure device is connected to the sealed chamber via a connecting pipe. Beneficial effects

[0013] 1. The above-mentioned bending test machine seals the wire rope inside the sealed chamber by setting a connecting mechanism. Then, by setting a salt spray mechanism, a temperature and humidity monitoring mechanism, and a hydraulic pressurization mechanism, the temperature, humidity, salt spray, water pressure, etc. inside the sealed chamber are regulated. This integrates multiple environmental factors such as temperature, humidity, salt spray, and water pressure inside the sealed chamber, thereby comprehensively and realistically reproducing the multi-environment coupling conditions in the actual use of the wire rope.

[0014] 2. The bending test machine described above moves the sealing disc away from the sealing box, thereby pulling the outer locking ring out of the sealing box. The outer locking ring then pulls the inner locking ring out of the sealing box through the connecting column. The steel wire rope is then fixed between the outer and inner locking rings. The outer and inner locking rings are then inserted into the sealing box, and the sealing disc contacts the sealing box, ensuring the sealing inside the sealing box. At the same time, the limiting block is engaged in the corresponding limiting groove, thereby ensuring the stability of the outer and inner locking rings inside the sealing box.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a wire rope bending testing machine.

[0020] In one embodiment, a wire rope bending test machine includes: a test mechanism 100, which includes a test bench 101, a sealed box 102, bending wheels 103, and a drive assembly for moving the bending wheels 103. The sealed box 102 is disposed on the upper surface of the test bench 101. The drive assembly includes a mounting frame 104, a motor 105, and a lead screw 106. The mounting frame 104 is fixedly disposed inside the sealed box 102, and the lead screw 106 is rotatably disposed inside the mounting frame 104, with the top end of the lead screw 106 rotatably penetrating through the sealed box 102. The motor 105 is disposed on the upper surface of the sealed box 102, and the output end of the motor 105 is keyed to the top end of the lead screw 106. The drive assembly also includes a connecting rod 107 and a moving block 108. The moving block 108 is configured as a convex block, and the moving block 108 is threaded onto the outer arc surface of the lead screw 106. The moving block 108 is connected to two sets of bending wheels 103 through the connecting rod 107. In this embodiment, the lead screw 106 is sealed through the sealed box 102 and connected to the motor 105. The motor 105 is located outside the sealed box 102 to prevent the environment inside the sealed box 102 from damaging the motor 105. When the motor 105 is started, it drives the lead screw 106 to rotate. The lead screw 106 drives the moving block 108 to move through the thread. The moving block 108 is set as a convex block to ensure that the moving block 108 will not rotate with the lead screw 106. Then, the moving block 108 drives the two sets of bending wheels 103 to move up and down through the connecting rod 107, thereby achieving the effect of bending the wire rope and facilitating the adjustment of different bending angles of the wire rope.

[0021] like Figure 3 , Figure 4 and Figure 5 As shown, the connecting mechanism 200 includes an outer locking ring 201, an inner locking ring 202, and an installation assembly. A steel wire rope is provided between the outer locking ring 201 and the inner locking ring 202. The installation assembly includes a connecting post 203, a sealing disc 204, and a limiting block 206. The connecting post 203 is connected to one side of the outer locking ring 201 and the inner locking ring 202, respectively. The side of the sealing box 102 has a moving groove corresponding to the outer locking ring 201 and the connecting post 203. The sealing disc 204 is located on the outer locking ring 201 away from the inner locking ring 202. On one side of the locking ring 202, and the sealing disc 204 is located outside the sealing box 102, two sets of limiting blocks 206 are provided. The two sets of limiting blocks 206 are fixedly set inside the sealing box 102, and the limiting blocks 206 are convex blocks. The outer locking ring 201 and the inner locking ring 202 are both provided with limiting grooves 205 corresponding to the limiting blocks 206 on their sides. The outer locking ring 201 and the inner locking ring 202 are located between two sets of bending wheels 103, and the outer locking ring 201, the inner locking ring 202 and the bending wheels 103 are located on the same vertical plane. In this embodiment, the outer locking ring 201 and the inner locking ring 202 are existing structures for locking the wire rope. The outer locking ring 201 and the inner locking ring 202 are pulled out, and then the wire rope is fixed between the outer locking ring 201 and the inner locking ring 202. Then, the outer locking ring 201 and the inner locking ring 202 are inserted into the sealed box 102, with the bending wheel 103 located on both sides of the outer locking ring 201 and the inner locking ring 202, thus ensuring that different bending patterns of the wire rope can be tested. When the outer locking ring 201 and the inner locking ring 202 are inserted into the sealed box 102, the two sets of limiting blocks 206 will respectively engage with the limiting grooves 205 on the sides of the outer locking ring 201 and the inner locking ring 202, thereby limiting the outer locking ring 201 and the inner locking ring 202. At the same time, the sealing disc 204 will be engaged on the outside of the sealed box 102, thereby ensuring the sealing performance inside the sealed box 102 and thus ensuring the accuracy of simulating various environments inside the sealed box 102.

[0022] like Figure 1 and Figure 2 As shown, the salt spraying mechanism 300 includes a nozzle 301 and a water tank 302; the temperature and humidity monitoring mechanism 400 is located on the outside of the sealed box 102; the hydraulic pressurization mechanism 500 includes a pressurizer 501 and a connecting pipe 502; the water tank 302 is located on the side of the sealed box 102, the nozzle 301 is located inside the sealed box 102, and a water pump corresponding to the nozzle 301 is installed inside the water tank 302; the pressurizer 501 is located on the upper surface of the test bench 101, and the pressurizer 501 is connected to the sealed box 102 through the connecting pipe 502. In this embodiment, a water pump inside the water tank 302 is connected to a nozzle 301, thereby spraying salt mist into the sealed box 102 through the nozzle 301. The temperature and humidity inside the sealed box 102 are monitored and adjusted by a temperature and humidity monitoring mechanism 400. The pressure inside the sealed box 102 is controlled by a pressure booster 501 and a connecting pipe 502, thereby adjusting the temperature, humidity, salt mist, water pressure, etc. inside the sealed box 102. This integrates multiple environmental factors such as temperature, humidity, salt mist, and water pressure inside the sealed box 102, thus comprehensively and realistically reproducing the multi-environment coupling conditions in the actual use of wire rope.

[0023] Working principle: The outer locking ring 201 and inner locking ring 202 are pulled out, and the steel wire rope is fixed between them. Then, the two sets of bending wheels 103 are moved to both sides of the outer locking ring 201 and inner locking ring 202. Next, the outer locking ring 201, inner locking ring 202, and steel wire rope are inserted into the sealing box 102. The limiting block 206 then limits the movement of the outer locking ring 201 and inner locking ring 202, and the sealing disc 204 ensures stability. The sealing performance of the sealing box 102 is verified. Then, the temperature, humidity, salt spray, and water pressure inside the sealing box 102 are adjusted by the salt spray mechanism 300, the temperature and humidity monitoring mechanism 400, and the hydraulic pressurization mechanism 500. Then, the motor 105 is started to drive the lead screw 106 to rotate. The lead screw 106 drives the two sets of bending wheels 103 to move through the moving block 108, thereby bending the steel wire rope. In this way, the multi-environment coupling working conditions of the steel wire rope in actual use are fully and realistically reproduced.

[0024] It should be noted that the motor 105, salt spray mechanism 300, temperature and humidity monitoring mechanism 400, and pressurizer 501 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the motor 105, salt spray mechanism 300, temperature and humidity monitoring mechanism 400, and pressurizer 501 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
